Easiest way to test your gloves, is to roll them up on a smooth surface (like your truck hood).
Roll them from the cuff end, trapping some air in them, if you get to the top of the palm of the glove, with no resistance felt, the gloves have a hole in them.
This means the glove is no longer fit for safe use and should be got rid of.
It says in my contract with my employer, that I shall make sure that the gloves and outers MUST be kept in the container provided for them, never expose them to sunlight for any length of time and never be stowed with other tools that may puncture or damage them.
